Multi-hued purity

A multi-layered, multi-hued work of genius that ensures that the colored top of each playdough container is at best a close approximation to what's actually inside.

Robert's fun with playdough highlights one of the aspects of genius that runs counter to hyper-specialized society: the best works of art are usually a meld of many separate things, and once you've joined them, they never come apart quite the same again; a little color always gets left behind to add to the mix.
